Correct but please bear in mind I still don&#39;t have a 26 or 28 cm crossover/freeride fin yet to prove or disprove it.
The crossover 24 cm fin felt a bit too small whereas a 30 cm freeride fin (from Kombat 86) felt a bit too large for my taste @65 kg with my NR 6.2 sail and the freeride footstrap&#39;s setup. Since you&#39;re heavier than me, I would strongly suggest you try several fin sizes before buying if you can.
